MINE-CAR WHEEL.

Specification of Letters Patent. Application filed March 4, 1912. Serial No. 681,530.

The wheel and axle, of which a portion are shown in the drawing,are of that type Be it known that we,

111 which the end ofthe a 'le is reduced 1n Ronan'r F. Pnrnurs and Louis J. MoCLosnEY,

citizens of the United States, residing at Garrick Borough, size and projects through an opening 1n a in the county of Allegheny and State 0t cap formed integral with the hub of the wheel, but our invention can be em loyed equally as well with wheels of the or inary type in which the end of the axle, on which the wheel turns, is of uniform diameter.

The axle is designated 1, and is formed with the reduced outer end portion 2. The axle 1, is a fixed axle, being secured to the car, and the wheel rotates thereon. The hub ortion .3, of the wheel shown in the drawlennsylvania, have invented certain new and useful Improvements in Mine-Car Wheels,'of which the following is a specifi; cation, reference being had therein to the accompanying drawing.

This invention has relation to mine car wheels of that class wherein a stationary axle and rotating wheel are employed and the object of this invention is to provide novel means for preventing wear of the ng, is formed with the integral ca 4,havlinch pm, which secures the wheel on the mg the central openlng 5, througi which projects the reduced outer end portion 2, of the axle 1. The linch pin, designated 6, is shown in the form of a cotter axle.

In the ordinary construction a flat washer is interposed between the rotatingwheel and the linch pin and this washer rotates with the wheel and soon wears out the linch pin so that it is liable to break and allow the wheel to come off the axle.

In our invention we form the washer with projecting lug? that engage the linch pin and prevent t e washer from rotating with the wheel, whereby all wear is imposed on the washer, thus protecting the from being worn pin, that is a section of half round metal doubled on itself and having its ends spread apart to retain it in position in the hole in ,the axle through which it passes, but we wish it to be understood that a straight or tapering solid linch pin may be employed if desire A washer 7 is arranged on the axle between the linch pin and the wheel and this washer is formed with integral lugs 8, on its outer side, these lugs being at such distance apart as to receive the linch pin 6, between them and their purpose is to prevent the washer from rotating and thus imposing wear on the. linch pin.

The washer is shown separately in Figs. 4 and 5, and is preferably composed of comparatively soft metal, such as wrought iron linch pin and preventing it out.

We have illustrated our invention in the accompanying drawing wherein:

Figure 1 is a side elevation of part of a wheel with our improvement thereto. Fig. 2 is an elevation of the parts shown in Fig. 1, taken at right angles to Fi 1, the fragmentary portion of the whee? shown in this or steel and the lugs S, 8, are preferably fi are being in section. Fig. 3 is a plan view formed by upsetting or punching outwardly of the parts shown in Figs. 1 and 2, the pora part of the material of which the washer tion of the wheel shown being also in secis composed, so as to form the la 5 integral tion. Fig. 4 is a front elevation on an enwith and upset or punched from t ie body of the washer. These lugs closely embrace and fit partly around the linch pin and serve to hold the washer and linch pin in relatively fixed position and thus prevent wear of the larged scale of the washer shown in the above named fi ores, and Fig. 5, is a sec tional view of tie washer on the line ilk-fill of Fig. 4:.

en the washer becomes wornthe linch pin can be removed and the worn washer can 5 be readily removed and replaced.

claim The combination "with a Wheel, an axle, a malleable washer arranged on the axle and a linch pin passing through the axle, the

10 Washer being provided with integral lugs bent outward y to engage both sides of the lmch pin.

In testimony whereof we aifix our signatures in presence of two Witnesses.
